Executive Summary Overview This report presents and summarizes monitoring and compliance data collected

and analyzed by the Massachusetts Water Resources Authority’s (MWRA) Environmental Quality Department (ENQUAD) from July 1, 2003 to June 30, 2004. This report, while not a regulatory requirement, provides a useful documentation of influent and effluent quality trends over the course of a fiscal year for the MWRA’s Deer Island Treatment Plant (DITP) and Combined Sewer Overflow (CSO) facilities.

Deer Island Treatment Plant

The MWRA’s NPDES permit requires the Authority to monitor its wastewater treatment plant at Deer Island for specific parameters. The MWRA currently operates under a permit issued in July 10, 2000 and effective August 9, 2000. The permit calls for secondary treatment of wastewater and monitoring of the effects of the new outfall in the Massachusetts Bay. Secondary treatment began at DITP in August 1997 with the start-up of the first battery of secondary treatment (Battery A). In March 1998, Battery B was brought on-line. The final battery, Battery C, became operational in March 2001. In addition to the completion of secondary treatment facilities, the MWRA opened on September 6, 2000 a new 9.5-mile outfall tunnel that carries treated wastewater from DITP to Massachusetts Bay. The permit requires extensive monitoring of Massachusetts Bay to determine the effects of the outfall, if any exist. Figure 1 shows the Deer Island flow during each month of FY04, comparing the flow with the monthly averages of the previous twelve years – FY92 to FY03. From FY99 to FY02 all flows were treated at Deer Island, while from FY92 to FY98 flows were treated at DITP and the former Nut Island Treatment Plant, now the headworks for South System influent to DITP.

Restrictions on dry day flow are also part of the permit. These restrictions act to control new connections, ensuring that the collection system and the new treatment plant retain adequate capacity. Monthly dry day flows are calculated by averaging the flows on dry days over the previous year. A dry day is defined as a day with 0.09 inches of precipitation or less and no snow melt with the following restrictions: the precipitation on the previous day is less than 0.3 inches, the precipitation two days prior is less than 1.0 inch, and the precipitation three days prior is less than 2.0 inches. A day with snowmelt is defined as a day when there is snow on the ground and the air temperature is above 32oF. Figure 2 shows the dry day flow for Deer Island during each month of FY04. The solid line represents the dry day flow limit of 436 mgd for the permit. In FY04, no violations of the dry day flow limit occurred.

FY04 Permit Limit (436 MGD)

Since the new primary treatment plant came on-line on January 21, 1995, appreciable improvements have been seen in effluent quality. The removal rates for both TSS and BOD or cBOD (cBOD has replaced BOD in the current permit as the measure of oxygen demand) have improved significantly (see Figures 3 and 4, respectively on the following page). In FY96 and FY97, removal efficiencies compared favorably to theoretical removal efficiencies for primary treatment. In FY98, efficiencies continued to improve, especially for BOD, with a removal rate well above the theoretical range.1 This coincided with the start-up of Batteries A and B of secondary treatment. Since FY00, removal rates for both TSS and cBOD have leveled off as DITP has reached its optimal efficiency level.

Annual numbers of NPDES violations have decreased dramatically due to improved treatment at DITP. Figure 5 (next page) compares the number of NPDES permit violations at Deer Island in FY04 to previous years. No non-toxicity NPDES violations occurred in FY00, FY99, or FY97. One non-toxicity violation occurred in FY02 and FY98, three in FY03, and four in FY01, compared to 12 in FY96 and 19 in both FY95 and FY94. In FY04, one violation of the fecal coliform limit occurred at DITP. Details of that violation can be found in Chapter 2, Section II.B.

Since the opening of the new plant, Deer Island has seen significant reductions in loadings of metals and organic compounds in the effluent – see Chapter 2 for more details. These improvements are probably due to two factors: first, corrosion control activities and source reduction programs have helped to lower these pollutants in the incoming influent. Second, the new plant is able to better capture both metals and organics in the treatment process.

Combined Sewer Overflow Facilities

MWRA monitors five CSO facilities – Cottage Farm, Prison Point, Somerville Marginal, Fox Point, and Commercial Point – under the permit. The Constitution Beach facility is also included under the permit. However, MWRA decommissioned the Constitution Beach facility in September 2000 following the completion of a sewer separation project in East Boston. Figures 6 and 7 on the next page show the number of activations and the total volume treated, respectively, at the six CSO facilities since FY92. The correlation between rainfall and CSO activation can be seen in both figures. Note that although total rainfall is correlated to CSO activations, the intensity of the rainfall and frequency of storms will have an important effect. These characteristics influence the degree of ground saturation, affecting the volume treated at the CSO facilities during a storm.

Collection and Transport System

The MWRA monitors the capacity of the wastewater collection and transport system. One of the system capacity parameters in the North System is choking, which occurs at the remote headworks. Choking is a reduction or stopping of flow to Deer Island at the remote headworks, either when heavy flow exceeds the capacity of the treatment plant or when maintenance or construction is performed at the plant. As Figure 8 on the following page shows, the number of hours of choking has fallen to very low levels since FY01, mainly due to the completion of the Deer Island plant. To minimize choking related to testing and maintenance, MWRA performs maintenance and testing at off-peak times so not to cause any backups in the system upstream of the headworks.

Heavy Rain & Flow Testing & Maintenance

The MWRA also monitors the occurrence of Sanitary Sewer Overflows, or SSOs, associated with MWRA-owned sewer lines. These overflows occur in areas where the collection system becomes overloaded by heavy flows. In FY95, the MWRA’s Transport Department started to locate and visually monitor these SSOs in the North and South Systems. Table 1 lists the SSOs observed by MWRA personnel in FY04.

Future Outlook

The startup of the new primary treatment plant at Deer Island in FY95 was just the first of several changes and improvements in the MWRA’s facilities, including full secondary treatment, the Inter-Island Tunnel linking the South System to DITP, and the new outfall tunnel to Massachusetts Bay. The MWRA no longer discharges effluent into Boston Harbor and the Authority is currently monitoring the effects of these changes on water quality in the Harbor and Massachusetts Bay, as required by the NPDES permit issued in July 2000. In addition, a contingency plan ensures that the discharge does not adversely impact Massachusetts Bay. Major upgrades are finished at the five CSO facilities, although construction of a sixth facility, Union Park, will be completed in early 2006. Several upgrades were also finished at the Quincy and Squantum pump stations in 2002 and 2003, respectively. Finally, the Braintree-Weymouth Intermediate Pump Station was brought on-line in 2004, increasing pumping capacity to DITP. This increased capacity should reduce sanitary sewer overflows to Smelt Brook. Taken as a whole, these upgrades have modernized MWRA facilities and reduced pollutants discharged to receiving waters.

I: Introduction Overview This report presents and summarizes the NPDES monitoring and compliance

data compiled and analyzed by the MWRA Environmental Quality Department during the period of July 2003 to June 2004. MWRA's DITP and CSO facilities serve large communities’ needs for sewer systems while maintaining healthy water environments for recreation and wildlife. Chapter II presents and discusses the monitoring results for DITP, along with Contingency Plan and Ambient Monitoring Plan requirements. Chapter III describes the results for the five CSO facilities. Chapter IV discusses sludge processing operations at DITP and the MWRA’s Fore River pelletizing facility. Chapter V discusses transport and sewer system capacity issues. Finally, Chapter VI covers an array of miscellaneous topics introduced by the new permit. Appendices A-F provide detailed monthly data for the Deer Island plants and for the five CSO facilities. Appendix G provides background information about MWRA’s regulatory requirements, and Appendix H describes the MWRA sewer system and facilities. Appendix I defines the types of detection limits encountered in chemical analyses. Appendix J lists pollutants of concern. Finally, Appendix K is a glossary of the terms and phrases used throughout this report.

II: Deer Island Treatment Plant

Overview This chapter presents and discusses monitoring information for DITP. The characteristics examined include flow, conventional parameters, nutrients, priority pollutants (metals, cyanide, pesticides/PCBs, and organic compounds), fecal coliform bacteria, and whole effluent toxicity. Since a number of limits in the Contingency Plan set forth by the new NPDES permit deal with effluent quality, this section finishes up with a description of the Contingency Plan and the closely related Ambient Monitoring Plan.

II.A.1 Influent Flow

The average flow to DITP in FY04 was 355.6 million gallons per day (mgd). Figure II.A.1 shows that flow generally rises and falls with the amount of precipitation. This occurs because several of the larger communities in the North System (Boston, Cambridge, Somerville, and Chelsea) have combined sewers.

The impact of rainfall on flows can also be seen in Figure II.A.2 on the following page, which tracks average flow and precipitation over the past twelve fiscal years. The completion of the Inter-Island Tunnel from Nut Island to Deer Island in early FY99 resulted in increased flow to DITP, as DITP treated South System sewage previously treated at the Nut Island Treatment Plant. A slight drop in rain in FY04 (42.04 inches versus 43.51 inches in FY03) may have lead to the slightly lower average flows to DITP in the past fiscal year.

II.A.3 Influent Priority Pollutants

The results of a complete priority pollutant scan of Deer Island influent can be found in Tables A-2 and A-3 of Appendix A. For levels below detection limits, one half of the method detection limit for inorganic compounds or one tenth of the quantitation limit for organic compounds was substituted to calculate concentrations and loadings. Appendix I provides a detailed discussion of detection and quantitation limits. A pollutant is included whether it was detected just once or 37 times over the course of a year. Figures II.A.3 and II.A.4 below show annual averages of the daily loads; however, they do not truly reflect how often the pollutant was detected during the year. Therefore, if a below detection limit concentration is converted to a loading, it is recorded as a non-zero value, even though the constituent may not have been present in the sample. Note that these caveats apply to both metals and organics loadings. However, since metals are commonly detected in almost every sample, the notes raised above are less of an issue. Figure II.A.3 compares FY04 average influent loadings for several key metals

to historical values. The MWRA samples for these pollutants a few times a month. Using the measured concentration and the flow on the day on which the sample was taken, daily loads can be calculated. Data from FY98 and earlier is from the North System only. Before 1999, metals loadings in the North System decreased steadily, as MWRA made strides in toxic and corrosion control efforts involving both water supply and wastewater transport. Since the South System flow was transferred from Nut Island to Deer Island at the start of FY99, the data after FY99 includes the South System flow. This larger, combined flow explains the increase in metals loadings from FY92-98 to FY99-04. Since loadings are calculated using flow, which in turn is affected by rainfall, loadings can rise and fall with rainfall amounts.

Table II.A.4, on the next page, shows how degree of secondary treatment can affect TSS and cBOD removal efficiencies. The table lists TSS and cBOD removal efficiencies and the percentage of flow that received secondary treatment on a monthly basis. The degree of secondary treatment is the average flow through secondary treatment (mgd) during the month divided by the average plant flow (mgd) for that month. For the fiscal year, 92% of DITP flow went through secondary treatment and removal efficiency for TSS was 93%. For cBOD, the plant achieved 90% removal efficiency.

Table II.A.5 (next page) summarizes the conventional parameters and nutrients in Deer Island effluent over the past nine years. The significant drop in several parameters that occurred between FY95 and FY96 is due to the improved removal efficiency of the primary treatment plant. The implementation of secondary treatment in FY98 can explain the drop in TSS and BOD concentrations since FY97. Secondary treatment is also responsible for the increase in ammonia concentrations over the same period.

Table II.A.5. Deer Island Effluent Characterization, FY94-FY04

A summary of nutrient concentrations in Deer Island effluent from FY94-FY04 is provided in Figure II.A.5 on the following page. The introduction of the new primary treatment plant in FY95 did not affect nutrient concentrations, as primary treatment has no effect on nutrients. However, the activated sludge process used in DITP’s secondary treatment does change nutrient concentrations. The activated sludge process uses bacteria to promote efficient and rapid breakdown of wastes. This bacterial breakdown results in changes in the proportions of nitrogen species. For example, total Kjeldahl nitrogen (TKN) consists of NH3-N plus organic nitrogen. Effluent NH3-N concentrations have risen while total Kjeldahl nitrogen (TKN) concentrations have remained relatively stable. Therefore, the proportion of NH3-N as a TKN component has increased. Elevated levels of NH3-N are characteristic of the activated sludge process.

II.A.5 Effluent Priority Pollutants

Appendix A, Tables A-8 and A-9 provide a summary of priority pollutant concentrations and loadings in DITP effluent for FY04. For a discussion of the importance of detection limits in loading calculations, see Section II.A.3 and Appendix I. Metals loadings over the past fifteen years are summarized in Figure II.A.6, while Figure II.A.7 on page 17 graphs organic pollutants from FY94-FY04. Two factors may explain the long-term decrease in loadings. First, the MWRA has instituted a more aggressive industrial pre-treatment program coupled with stricter enforcement of local limits. Second, the decrease may also be attributed to better capture of metals and organics at the plant.

II.A.6 Whole Effluent Toxicity

The MWRA tests effluent toxicity every month at DITP. Effluent toxicity provides an overall view of effluent quality, ensuring that the effluent does not adversely affect the environment. In 1989, the EPA found that surfactants were the probable cause of most acute toxicity in DITP’s effluent. Surfactants are most commonly used in household detergents to improve cleansing power. No acute toxicity could be attributed to metals or pesticides. The MWRA permit requires four tests for effluent toxicity testing. 48-hr acute static toxicity tests using the mysid shrimp (Americamysis bahia) and the silversides fish (Menidia beryllina) measure the short-term lethal effects caused by the effluent. A chronic survival and growth test using Menidia and a chronic fertilization test using the sea urchin (Arbacia punctulata) both measure subtle toxic impacts over a longer period of time. The results of these tests for FY03 can be found in Table II.A.6 on the following page. The LC50 (Lethal Concentration 50%) is the concentration of effluent in a sample that causes mortality to 50% of the test population during the duration of the test. The two acute tests use LC50. The NOEC (No Observed Effect Concentration) used in the chronic tests is the concentration of effluent in a sample to which organisms are exposed in a life cycle or partial life cycle test that has no adverse effects. An NOEC limit of 1.5% means that 1.5% of the sample is effluent, and the remainder dilution water. Any acute LC50 below 50% or chronic NOEC below 1.5% would violate the NPDES limit.

Deer Island Effluent, Results of Toxicity Testing, FY04

II.B.1 Compliance with Regulatory Limits

Plant performance at Deer Island is compared to permit limits in Table II.B.1 and Figures II.B.1 through II.B.9 on the following pages. The only violation of the regulatory limits in FY04 was for fecal coliform, which took place in April 2004. On April 2, 2004, the geometric mean of the three samples collected that day was 15,223 colonies/100mL, exceeding the permit limit of 14,000 colonies/100mL. Operations staff theorized that chlorine dose was not high enough to meet the high chlorine demand from the high flows on April 1 and 2 (on April 2nd, the average flow was 1,137 mgd). With a lower than needed dose, the required levels of bacterial kill were not achieved, hence the fecal coliform exceedance. Total chlorine residual levels on April 2 and the preceding and following days were essentially normal, and TSS levels were also unremarkable. Fecal coliform counts for April 1 and 3 were 2,525 and 153 colonies/100mL, respectively – both well below the permit limit.

Fecal coliform has a daily discharge limit of 14,000 colonies/100mL, as calculated by the daily geometric mean of three samples per day. In FY04, there was one violation of the daily fecal coliform limit, as detailed above. Figure II.B.5 shows the daily effluent trends of fecal coliform in FY04. Note that 5 colonies/100mL is the detection limit for the fecal coliform test so there will not be results below that number.

The limits for pH are based on the maximum and minimum values for each month, with pH required to fall between 6.0 and 9.0. In FY04, the pH of the effluent was always below the maximum of 9.0 and above the minimum of 6.0. Figure II.B.7 shows the monthly minimums and maximums throughout FY04.

There are two other effluent limits. Arochlors 1016, 1221, 1232, 1242, 1248, 1254, and 1260 have a 0.000045 µg/L limit. None of these compounds were detected in the effluent in FY04. The dry day flow limit was covered in the Executive Summary, and the Executive Summary’s Figure 2 on page 2. MWRA must also report a number of other effluent components, although they have no discharge limit. These are listed in Appendix G, Table G-1.

II.C.1 Ambient Monitoring Plan

The new permit requires ambient monitoring of the Harbor and Massachusetts Bay. The ambient monitoring plan has three main components: the Harbor and Bay monitoring plan; the maintenance of the Bays Eutrophication Model; and the implementation of plume tracking. Table II.C.1 summarizes the first and third components of the monitoring plan. Note that the plume tracking component of the plan is now completed and results are available from ENQUAD. The Bays Eutrophication Model is a three-dimensional hydrographic model that is run annually to provide information on whether new limits are needed on the effluent discharge. The Model is designed primarily to examine nutrient inputs. In March 2004, the MWRA issued Revision 1 of the ambient monitoring plan, which made minor changes to the original plan. Highlights included reducing the number of nearfield and benthic monitoring stations, reducing the number of nearfield surveys, as well as exploring the possibility of real-time monitoring using permanent moorings.

The Outfall Monitoring Science Advisory panel (OMSAP), a panel of scientific experts convened by the EPA and MA DEP, oversees the monitoring plan and examines scientific data produced by the MWRA and MWRA consultants. OMSAP also serves as a peer review board for technical reports, and advises EPA and MA DEP on the implications of monitoring observations. Finally, OMSAP evaluates any exceedances under the Contingency Plan, described in the next section. Much more information on the ambient monitoring plan is available on the Internet. Documents directly associated with the permit, including Revision 1 of the ambient monitoring plan, can be found at: http://www.mwra.state.ma.us/harbor/html/ambient.htm Associated information and synthesis reports generated by ambient monitoring results can be found at: Boston Harbor: http://www.mwra.state.ma.us/harbor/html/wklyintr.htm Massachusetts Bay: http://www.mwra.state.ma.us/harbor/html/mbmon.htm The OMSAP web page, including announcements for public meetings, is at: http://www.epa.gov/region1/omsap/index.html

II.C.2 The Contingency Plan

The permit requires a contingency plan that defines a response plan when a parameter threshold is exceeded. Reponses may include changes in laboratory procedures, changes in treatment plant process, or, in a worse case scenario, examining the feasibility of re-opening the Deer Island harbor outfalls. Tables II.C.2.a-c show the thresholds for the parameters. The effluent and toxicity thresholds are set to be equal to the NPDES permit limits. However, the Contingency Plan includes a number of new thresholds related to parameters monitored under the Ambient Monitoring Plan in Massachusetts Bay.

Table II.C.3. Contingency Plan Exceedances, FY04

* Notification date; typically within 5 days of knowing of the violation. In addition to the thresholds, the Contingency Plan also requires several other unrelated items. First, the MWRA must update annually a technical survey regarding tertiary treatment systems designed to remove nutrients. Second, the Authority must maintain a nitrogen monitoring program at DITP to examine the need for tertiary treatment. Both of these efforts are ongoing. Third, there must be a “dry run” of a Contingency Plan violation to assess the validity of the Contingency Plan structure. Fourth, $81 million must be held in reserve for emergency use. Finally, the old Boston Harbor outfalls must be maintained in case diversion of the effluent back to the Harbor is deemed necessary. These last three options have been successfully completed. More information on Contingency Plan topics is on the Internet at: http://www.mwra.state.ma.us/harbor/html/contingency.htm Exceedance reports are posted at: http://www.mwra.state.ma.us/harbor/html/exceed.htm

III: Combined Sewer Overflows

Overview MWRA monitors five CSO facilities in the North System. There are no CSO facilities in the South System. The monitoring results vary significantly between facilities because of differences in type and location. Location is especially important since storms can be highly localized, affecting the level and intensity of rainfall at the CSO facility and the area that the facility serves. Improvements to the transport system and the CSO facilities themselves have improved the capture of combined sewage. This is resulting in the somewhat paradoxical observation that although the facilities are having fewer activations, the average amount discharged per activation is rising. To counteract the larger amounts of combined sewage being captured, each CSO facility screens and chlorinates combined wastewater (sewage and storm water) prior to discharge. The Cottage Farm and Prison Point facilities also have pumping and tank storage capacity. Pumping and tank storage allows screened and chlorinated wastewater to be held at these facilities up to their storage capacities prior to discharge. Stored wastewater can eventually be pumped back into the system and processed at Deer Island. Any wastewater exceeding the storage capacity will overflow and discharged through the CSO outfalls. The other three CSO facilities – Somerville Marginal, Fox Point, and Commercial Point – are gravity CSO facilities, meaning that combined wastewater arrives and leaves the CSO facility by gravity instead of pumping. The combined wastewater is screened, chlorinated, and dechlorinated. The disinfected wastewater overflows to the receiving water as quickly as it arrives at the facility. A detailed description of the five CSO facilities can be found in Appendix H.

31

III.A.1 Cottage Farm Activations

Table III.A.1 and Figures III.A.1 and III.A.2 summarize activation data for the Cottage Farm CSO facility. Cottage Farm is hydraulically connected to Deer Island, so the increased pumping capacity at Deer Island is partially responsible for the general trend of decreasing activations since FY94. From FY03 to FY04, releases from Cottage Farm increased from 116.7 to 209.2 million gallons. Number of activations remained about the same, as did rainfall. This combination suggests that FY04’s rainfall was distributed as a small number of intense rainstorms, which greatly increase the volume discharged by the CSO facilities. Additionally, improvements to the collection system resulted in greater capture of combined sewage flows. A near doubling of the average flow per activation in FY04 compared to FY03 supports this hypothesis.

III.A.2 Cottage Farm Conventional Parameters

Table B-1 of Appendix B contains detailed data on conventional parameters in Cottage Farm effluent. Table III.A.2 below summarizes this data. As is the case with all five facilities covered in this chapter, Cottage Farm is a CSO facility that provides floatables control, chlorination, and dechlorination. Such a facility cannot provide the same level of effluent treatment as a full-fledged treatment plant such as Deer Island. CSO effluent pH is often rather low in comparison to effluent from Deer Island or other treatment plants as CSO facilities cannot correct for sewage that enters the facility with an already low pH.

III.A.3 Cottage Farm Effluent Metals

For permit compliance, MWRA tests CSO effluent for metals and surfactants whenever the CSO facility is sampled. The results of these tests are presented in Appendix B, Tables B-2 and B-3. The target metals were detected in nearly every sample. Table III.A.3 summarizes average metal concentrations in Cottage Farm effluent in FY04.

III.B.1 Prison Point Activations

Activation data for the Prison Point CSO facility are summarized in Table III.B.1 and Figures III.B.1 and III.B.2. Unlike the Cottage Farm facility, Prison Point is not hydraulically connected to the Deer Island Treatment Plant, so increased pumping at Deer Island will not affect Prison Point activations; hence they have remained relatively constant since FY94, primarily dependent on rainfall. The amount discharged by Prison Point increased a small amount in FY04 compared to FY03. The number of activations decreased fairly sharply, leading to a substantial increase in the average amount discharged.

III.C.1 Somerville Marginal Activations

Table III.C.1 and Figures III.C.1 and III.C.2 summarize activation information for the Somerville Marginal facility. Recently, there has been increased attention to SSOs (Sanitary Sewer Overflows); see Chapter V for more information. MWRA has intensified its monitoring efforts at areas known to overflow where there is a measurable rainfall event. In coordination with this increased SSO monitoring, MWRA has monitored its unmanned gravity CSO facilities of Somerville Marginal, Fox Point, and Commercial Point more frequently. As a result, the statistics for FY98 and after may not be strictly comparable to the earlier years. In FY04, the volume discharged at Somerville Marginal increased dramatically, although less activations were recorded. Average volume per discharge, however, more than doubled despite essentially the same level of rainfall as FY03. Differing storm patterns and intensities between the two years can possibly explain these discrepancies.

III.D.2 Fox Point Conventional Parameters

Appendix E, Table E-1, provides data on conventional pollutants collected at Fox Point in FY04. Results are summarized below in Table III.D.2. As explained in Section III.A.2, CSO facilities have no pH control mechanisms, so the pH of the effluent is wholly dependent on the influent pH. Hence, the operation of Fox Point cannot be blamed for the very low effluent pH of 4.2 seen in FY04.


Table III.D.2. Fox Point CSO Effluent Characteristics, FY04

III.D.3 Fox Point Effluent Metals

The results of sampling for priority pollutants at Fox Point can be found in Appendix E, Tables E-2 and E-3. Table III.D.3 summarizes the average metals concentrations in FY04.

III.E.1 Commercial Point Activations

Data on Commercial Point activations can be found in Appendix F, and in the table and two figures below. Commercial Point discharged substantially more effluent in FY04 than in FY03 – in fact, the most the facility has discharged since FY97. Average flows increased to more than double the flows of the previous fiscal year. Again, changes in storm patterns and intensities could be responsible for the increased volume discharged despite rainfall that was essentially the same as in FY03.

IV: Sludge Processing

Overview In December 1991, the MWRA ceased discharge of sludge into Boston Harbor. The sludge was then sent to a new plant located on the Fore River in Quincy for processing into fertilizer pellets.

IV.A Pelletizing Process

The pelletizing process begins at the Deer Island Treatment Plant, where gravity thickeners handle sludge and scum from the plant’s primary batteries. Centrifuges thicken secondary sludge and scum, with the help of added polymers. Centrate, or the liquid produced by these processes, is sent back to the head of the plant for treatment. The thickened product is then transferred to Deer Island’s most distinctive feature, the egg-shaped anaerobic digesters. In the digesters, bacteria break down the sludge into methane, carbon dioxide, organic material, and water. The methane is tapped, stored, and used later to generate electrical power or heat for Deer Island. The digested sludge is centrifuged again and then is barged across the Harbor to the Fore River Pelletizing facility. At the pelletizing plant, centrifuges dewater the sludge into “cake,” and dryers further process the sludge into the fertilizer pellets. The centrate from the centrifuges is barged back to Deer Island for treatment. The pellets, marketed as “Bay State Fertilizer,” are stored at the facility after production. They can either be packaged on-site, or loaded and shipped out in bulk by rail. Bay State Fertilizer is available in limited quantities to the general public, and is more widely available to local municipalities and for wholesale purchase. In the future, sludge will be transferred to the Fore River facility via one of two tunnels built inside the Inter-Island Tunnel, and a connection from Nut Island (the southern terminus of the Inter-Island Tunnel) to the pelletizing facility. Centrate will return to Deer Island via the second tunnel inside the Inter-Island Tunnel. These connections will obviate the need for barging sludge and centrate between the two sites.

IV.B Sludge Pellet Regulations

Both the federal government and the Commonwealth of Massachusetts have regulations for the composition of fertilizer pellets. The federal government regulates copper, molybdenum, nickel, zinc, arsenic, cadmium, lead, mercury, and selenium. Massachusetts sets limits for all of the above except arsenic and selenium, while adding limits for boron and chromium. In most cases the Massachusetts standard are tougher than the federal standards. Meeting these regulations has generally not been a problem for the MWRA or its contractor, New England Fertilizer Company. Table IV.B.1 (next page) summarizes the applicable standards.

42

Due to the February 19 annual submittal date for sludge data, complete data is not available for FY04 operations. However, in calendar year 2003 (CY03; the latest available data), there were no violations of federal standards for sludge pellets. In five months there were violations of the Massachusetts standard for molybdenum. Table IV.B.2 summarizes the analytical results. The plant processed 32,983 dry tons of sludge in CY03.

Heavy Rain & Flow Testing & Maintenance

Figure V.A.2 shows the influence of the number of rainy days in a year on the hours of rain-related choking. A rainy day is defined as a day with greater than 0.09 inches of rainfall. Differences in storm intensity between the years can explain years that have similar amounts of rainy days yet vastly different choking hours (i.e., FY96 versus FY98 and the three years of FY02-FY04).

Choking for maintenance purposes is plotted in Figure V.A.3. Maintenance choking peaked in FY95 due to the maintenance and testing involved in bringing the new primary treatment plant on-line. From FY96 to FY98 the number of hours of maintenance-related choking continued to be fairly high because of maintenance and testing related to the startup of the new primary and secondary treatment plants. For example, in FY98, of the approximately 580 choking hours related to testing and maintenance, 442 hours were due to testing. Since there were no new systems to test in FY99, there was a significant decrease in the testing/maintenance choking hours from FY98 to FY99. Testing and maintenance increased in FY01 due to the finishing of both secondary Battery C and the outfall tunnel. With no new systems post-FY02, choking due to testing and maintenance fell to minimal levels.

V.A.2 North System Sanitary Sewer Overflows

MWRA monitors sanitary sewer overflows (SSOs) visually and with meters in both the North and South Systems. SSOs occur when extreme rainfall overwhelms the transport system. Note that SSOs differ from CSOs (combined sewer overflows) in that CSO relief points are pipes that were specifically designed to relieve the combined sewer system. When the system becomes overloaded, these CSOs discharge combined sewage and storm water into a receiving body of water, such as the Charles River. SSOs, on the other hand, are weak points in the separate system, such as manholes, which will overflow during heavy rain events. There were nine reported overflows in FY04 for the North System (see Table V.A.1). However, this count includes only overflows at MWRA-owned overflow areas. There may be overflows for which the local municipalities are responsible. MWRA monitors these local overflows less frequently, and only when notified by municipalities or concerned citizens. A list of all the known overflow locations in MWRA lines is provided in Appendix H, Table H-4. FY04 had an increased number of overflows due to a 50-year storm that occurred between March 31 and April 2, 2004.

46

V.B South System Sanitary Sewer Overflows

There were nine overflows at two locations in the South System in FY04. Although the number of South System overflows in FY04 was comparable to FY03, some of the overflows at Smelt Brook can be directly attributed to the 50-year storm mention above.

V.C Inflow and Infiltration

Inflow and infiltration (I/I) is a potentially serious problem that affects all sewerage systems. The NPDES permit requires the MWRA to address issues associated with I/I. Inflow is defined as the introduction of non-sanitary sewer water such as stormwater, residential basement pump-out, and industrial cooling water, into sanitary sewers. Infiltration is the leakage of groundwater into sewage lines through cracks, inadequately sealed joints, etc. In both cases, this additional load decreases system capacity, potentially leading to SSOs. I/I poses both a wet and dry weather problem; however, wet weather exacerbates I/I problems. A summary of all actions minimizing I/I is prepared annually by MWRA. In addition, the MWRA participates in a Regional I/I Task Force responsible for creating a Regional I/I Reduction Plan for both MWRA and local community collection systems. The I/I Task Force includes MWRA staff, state regulators, and representatives from local communities. To reduce I/I, the MWRA “may consider incentive programs, rate structures, grant and loan programs, technical assistance and public education efforts as well as regulatory and enforcement mechanisms…” (permit section 18.bb.iv) At the end of FY03, MWRA submitted the Regional I/I Reduction Plan for regulatory review.

VI: Miscellaneous NPDES Permit Requirements

Overview The MWRA’s NPDES permit includes a number of other sections other than effluent quality for Deer Island and the CSO facilities, making it one of the most comprehensive permits ever issued by EPA.

VI.A Facility Best Management Practices Plans

Best Management Practices Plans (BMPs) are designed to minimize the environmental impact of MWRA facilities. The MWRA has developed plans for the following facilities:

• Deer Island Treatment Plant • Nut Island Headworks • Ward Street Headworks • Columbus Park Headworks • Chelsea Creek Headworks • Cottage Farm CSO facility • Prison Point CSO facility • Somerville Marginal CSO facility • Fox Point CSO facility • Commercial Point CSO facility • Fore River Pelletizing Plant

The objectives of BMPs are “(1) minimize the potential for violations of the permit, (2) protect the designated water uses of the surrounding water bodies, and (3) mitigate pollution from materials storage areas, site runoff, improper use of waste disposal system, accidental spillage, etc.” (permit section 9.a) BMPs are available at the above facilities or by request.

VI.B Water Conservation / Dry Day Flow Limit

As described in the Executive Summary, one of the requirements of the permit is the adherence to a 436 MGD dry day flow limit. In FY04, the MWRA was well within compliance for this limit. See Figure 2 in the Executive Summary for details. If dry day flow reaches 415 MGD, MWRA cannot accept new connections larger than 1.4 MGD. Additionally, a report is prepared annually documenting the MWRA’s demand management program. The demand management program, run with the cooperation of member communities, reviews historical water and wastewater use, and looks at the effectiveness of past and future conservation programs. Find permit-related water conservation and dry day flow limit materials at: http://www.mwra.state.ma.us/harbor/html/flow.htm

VI.C Pollution Prevention Program

The pollution prevention requirement of the permit requires MWRA to develop strategies to reduce pollutant loadings from households and permitted industries in the service area. The main target of the program is

http://www.mwra.state.ma.us/harbor/html/flow.htm

48

polychlorinated biphenyls, or PCBs, a known human carcinogen. Manufacture of PCBs has been banned for several decades; however, quantities remain in the environment. The other main aspect of the program is the development of educational materials regarding domestic household hazardous waste, with the aim of preventing those materials from entering the MWRA sewerage system through proper disposal techniques. For more information on the MWRA’s pollution prevention program, visit: http://www.mwra.state.ma.us/harbor/html/pollution.htm

VI.D Groundwater Remediation

Currently, groundwater remediation site waters cannot be discharged into the MWRA sewer system. If this prohibition is ever relaxed, a comprehensive assessment of its effects on the sewage system and treatment process is required. As of the end of FY04, no action has been taken on this section.

VI.E Local Limits and Industrial Pretreatment Programs

These two related programs deal exclusively with non-domestic users, which are primarily industry. Under the local limits program, the MWRA develops and enforces specific limits on effluent from industrial users. The industrial pretreatment program requires the MWRA to inspect and sample industrial users as specified by 40 CFR (Code of Federal Regulations) Part 403. 40 CFR Part 403 is designed as a source reduction program to limit the amount of pollutants in treatment plant influent. Both programs result in cleaner influent to Deer Island, reducing stress on the plant, improving the efficiency of the treatment process, and reducing “pass-through” of contaminants to the effluent. Additionally, the sludge produced is cleaner and more amenable to safe fertilizer production. More information on local limits and the pretreatment program is on-line at: http://www.mwra.state.ma.us/harbor/html/local.htm

VI.F Reporting

Finally, the permit also requires the MWRA to provide the public with easy access to permit compliance reports and other information. MWRA maintains a NPDES permit website at: http://www.mwra.state.ma.us/harbor/html/ditp_performance.htm EPA maintains an electronic mailing list for permit-related announcements: http://www.epa.gov/region1/eco/mwra/listserv.html Finally, there are two library repositories for permit documents: MWRA Library Hyannis Public Library Charlestown Navy Yard 401 Main Street 100 First Avenue Hyannis, MA 02601 Boston, MA 02129

Appendix G: NPDES Monitoring Requirements

Overview The Environmental Protection Agency (EPA) mandates that any discharge to a body of water must be permitted through the National Pollutant Discharge Elimination System (NPDES). The EPA and the Massachusetts Department of Environmental Protection (DEP) jointly issued a NPDES permit to MWRA for the Deer Island treatment plant and six CSO treatment facilities: Cottage Farm, Prison Point, Somerville Marginal, Constitution Beach, Fox Point, and Commercial Point. The limits set in the MWRA NPDES permit are limitations for secondary treatment plants. In March 2001, secondary Battery C underwent start-up at Deer Island, substantially finishing the construction process at the plant. Before the completion of Battery C, though, plant effluent was already largely in compliance with the new permit. Additionally, in September of 2000, Constitution Beach, one of the six permitted CSO facilities, shut down, leaving five permitted and operational CSO facilities. In addition, MWRA monitors the influent quality of wastewater. Those monitoring results provide the basis for determining the adequacy of existing local limits to protect the treatment plants and Boston Harbor. Local Limits, enforced by MWRA’s Toxic Reduction and Control (TRAC) department, allow the discharge of toxic chemicals from industrial sources to be regulated. The MWRA submitted proposed local limits in FY00 reflecting the new secondary treatment requirements. Regulators approved the new local limits and they became effective in June 2003, at the end of FY03. Under the pretreatment program requirements, local limits must be re-evaluated every five years. MWRA not only monitors to comply with the NPDES effluent requirements, but also has its own monitoring programs, including monitoring at DITP, Boston Harbor, and Massachusetts Bay. These monitoring programs serve to assure appropriate control of discharges to the system, to assure the most cost-effective wastewater treatment while meeting water quality standards, and to assure the quality of life of the organisms and health of the animal communities living in the receiving waters.

G.1 NPDES Permit

Under the NPDES permit, “in compliance with the provisions of the Clean Water Act, as amended, 33 U.S.C. §§ 1251 et seq., and the Massachusetts Clean Water Act, as amended, Mass. Gen. Laws, ch. 21, §§ 26-53, Massachusetts Water Resources Authority is authorized to discharge from MWRA Publicly Owned Treatment Works, Deer Island Treatment Plant, Deer Island, Boston, MA 02152 (Discharge serial number T01), which discharges to receiving waters located in Massachusetts Bay, which is adjacent to Cape Cod Bay, and a part of the Gulf of Maine; and from Combined Sewer Overflow Outfalls, which discharge to the Charles River, Inner Harbor, Mystic River, Boston Harbor, Dorchester Bay, Alewife Brook; in accordance with effluent limitations, monitoring requirements and other conditions set in the permit…”

G.1.a Monitoring Requirements and Effluent Limitations

The NPDES permit establishes monitoring requirements for the new Deer Island outfall tunnel (T01). The permit also regulates CSO treatment facility outfalls at Cottage Farm (MWR201), Prison Point (MWR203), Somerville Marginal (which has two outfalls from a single facility, the primary outfall, MWR205, and the relief outfall, MWR205A), Constitution Beach (MWR207, now closed), Fox Point (MWR209), and Commercial Point (MWR211). The permit also establishes a comprehensive receiving water monitoring plan, the Ambient Monitoring Plan, in Massachusetts Bay.

G.1.b Reporting Requirements

In addition to Deer Island and CSO monitoring requirements, the NPDES permit requires numerous reports on the state of MWRA sewerage and operational systems. These include reports on infiltration/inflow, CSO facilities and collection systems maintenance and inspection, operational upsets, dry weather and sanitary sewer overflows, operational bypasses, monthly Discharge Monitoring Reports (DMRs), and reporting on the effects of discharges through the Ambient Monitoring Plan. In addition, the Contingency Plan mandates a number of additional thresholds and stipulates actions needed if they are exceeded. Table G-1 presents a summary of the permit limits and monitoring requirements for Deer Island and Table G-2 does the same for the CSOs.

Tests involve using mysid shrimp (Mysidopsis bahia) and inland silverside (Menidia beryllina) in 48 hour acute toxicity tests. LC50 must be achieved in a solution that is 50% effluent.

C-NOECc C-NOEC tests involve larval inland silverside (Menidia beryllina) and sea urchin (Arbacia punctulata). Menidia tests involve a week’s worth of exposure to various effluent concentrations. The Arbacia toxicity test tests fertilization in the test organism. In both cases, no chronic effects must be observed in a solution composed of 1.5% effluent.

All other CSO facilities discharge to marine waters, so the acute test organisms are mysid shrimp (Mysidopsis bahia) and inland silverside (Menidia beryllina). LC50 results are reportable.

* No limit, but values reported to EPA and DEP. a There are two other fecal coliform limits. The first is that not more than 10% of the individual samples collected in a month can have a count higher than 14,000 colonies/100mL. Typically, given 3 samples a day, this means no more than 9 samples can have a count higher than 14,000 in a given month. The second limit is that no more than 3 consecutive samples can exceed 14,000 colonies/100mL. b LC50: the concentration of effluent in a sample that causes mortality in 50% of the test population at a specific time of observation. c C-NOEC: Chronic No Observed Effect Concentration is the highest concentration of effluent to which organisms are exposed in a life cycle or partial life cycle test which has no adverse effects (on growth, survival and reproduction).

G.2 Monitoring Programs

In FY04, MWRA conducted several monitoring programs. However, this report presents only the influent and effluent monitoring programs. The receiving water monitoring programs are too complex to cover in a single document. More information on monitoring in Massachusetts Bay and Boston Harbor can be found at: http://www.mwra.com/harbor/html/bhrecov.htm

G.2.a Treatment Plant Monitoring

Monitoring at DITP has two main components: influent monitoring and effluent monitoring. Influent monitoring characterizes the influent to the Deer Island Treatment Plant. Monitoring for conventional parameters is necessary for some parameters to meet NPDES reporting requirements, but monitoring many other parameters is critical for process control to ensure optimal plant functioning. Influent monitoring data provides influent loading rates and the basis for determining treatment plant efficiency. Influent monitoring for non-conventional parameters is an important part of MWRA’s source reduction and Local Limits program run by TRAC. Effluent monitoring characterizes the quality of the effluent discharged to Massachusetts Bay. With the addition of whole effluent toxicity (WET) testing, the parameters measured in the effluent are similar to those measured in the influent. The NPDES permit requires effluent monitoring and imposes permit limits on both conventional and priority pollutants to ensure the health of the receiving water. Additionally, the permit also requires the reporting of non-priority pollutants such as nutrients, although no limits are set on them. Table G-3 lists the treatment plant monitoring program parameters, including

http://www.mwra.com/harbor/html/bhrecov.htm

G-5

sample type, sampling frequency and analytical procedures used.

G.2.b Combined Sewer Overflow Facilities Monitoring Program

The CSO Monitoring Program includes influent and effluent monitoring at the five CSO facilities (the sixth, Constitution Beach, was closed in early FY01). Influent and effluent samples are collected and tested for conventional parameters at all five CSO facilities. Selected priority pollutants and metals are also analyzed in the effluent. Table G-4 lists the CSO monitoring program parameters, including sample type, sampling frequency and analytical procedures used.

G.2.c Sewer System Monitoring Program

The sewer system monitoring program, which attempts to identify Sanitary Sewer Overflows (SSOs), involves conducting visual inspections of areas in the separate sewer system that have a history of discharging during or shortly after a heavy rainfall event. Because of the hydraulics of the South System, discharges occur in manholes or other low-lying areas, while discharges in the North System are the result of combined sewage overwhelming sewage system capacity.

G.3 Treatment of Results

It can be difficult to interpret laboratory results to ensure that they are representative of the sample, especially when the results are at or below method detection levels. For the conventional parameters measured in these monitoring programs, calculating the average concentration of a particular parameter is straightforward: the arithmetic average is used. However, the concentrations of metals, pesticides and organics are frequently below method detection levels, and data are manipulated. Appendix J gives a brief description of method detection limits and how measurements below detection limits are treated in this report. Daily loadings (in lbs/day) were calculated using the formula:

34.8××= CQLoading Q = flow (mgd)

C = concentration (mg/L) 8.34 = unit conversion factor

To calculate monthly average concentrations for priority pollutants (metals, cyanide, pesticides/PCBs and organic compounds), the loadings of the pollutant during each sampling event for that month were added and then divided by the total flow during those events. Average annual concentrations were calculated using the same method, taking each individual sampling event into account in the calculation. It should be kept in mind that with the large flows going through the Deer Island Treatment Plant, taking one small sample might not always be truly representative. It is also important to keep in mind that certain parameters (conventional) were analyzed daily while other parameters (priority pollutants)

G-6

were analyzed only two or three times per month.

Appendix H: An Overview of the MWRA Sewerage System and Facilities

Overview The MWRA is responsible for the collection, transport, pumping, treatment,

and disposal of sewage in Boston and the greater Boston area. In addition to the Deer Island Treatment Plant, the MWRA operates another treatment plant, serving the town of Clinton and the Lancaster Sewer District, under special arrangements that originated when the Metropolitan District Commission (MDC) acquired land in Clinton for the Wachusett Reservoir. The Clinton Treatment Plant operates under a separate permit from the Boston NPDES permit and is not discussed in this report. The MWRA serves 43 communities with a total population of about two million people, 5,500 businesses, and 1,400 industries. More than 5,400 miles of town- and city-owned local sewers connect at over 1,800 points to over 230 miles of MWRA interceptor sewers. Also included in the vast sewerage system are twelve pumping stations, five headworks, over 80 combined sewer relief overflows and five CSO treatment facilities. Table H-1 lists the MWRA treatment facilities and relevant information pertaining to each facility. The Deer Island Treatment Plant in Winthrop serves the 43 communities in the metropolitan Boston sewerage system and is allowed to discharge under the Boston NPDES Permit. The sewerage system is divided into two major regions: the North and the South Systems. Table H-2 lists the sewerage service area population by community.

H-4

H.1 North System

The North System serves a population of about 1.3 million and is located to the north and west of Boston. It covers an area of about 168 square miles. Most of the North System is a separate system – different conduits carry sanitary wastewater and storm water. However, portions of Boston, Cambridge, Somerville, and Chelsea still have combined sewers, where the same conduits carry sanitary and storm water. Combined sewers serve about 20 percent of the North System service area. Community sewer lines tie into the MWRA system through interceptor lines that feed into the four headworks facilities in the North System. Two deep rock tunnels, the Boston Main Drainage Tunnel (BMDT) and the North Facilities Metropolitan Relief Tunnel (North Metro Relief), connect the three remote headworks to the North Main Pump Station (NMPS) on Deer Island. The seven-mile BMDT originates at the Ward Street Headworks, continues to the Columbus Park Headworks, and runs under Boston Harbor to the NMPS. The four-mile North Metro Relief Tunnel connects the Chelsea Creek Headworks to the NMPS. The two tunnels combined can handle approximately 800 mgd, matching the combined peak flow capacity of 788 mgd from the three remote headworks. A fourth headworks facility, the Winthrop Terminal, is located on Deer Island and receives flows from the city of Winthrop and the East Boston (Caruso) Pump Station through the North Metro Trunk Sewer. Figure H-1 on the next page shows the North System schematics. The MWRA North System has four pump stations. The Alewife Brook (64 mgd), Caruso (110 mgd), DeLauri (90 mgd), and Allison Hayes (11 mgd) pump stations convey wastewater to the headworks facilities. The four pump stations receive flow from interceptor lines as follows: Alewife Brook Pump Station Lexington Branch Sewer Alewife Branch Sewer Alewife Branch Conduit Caruso Pump Station Revere Branch Sewer East Boston Branch Sewer North Metro Relief Sewer* DeLauri Pump Station Cambridge Branch Sewer Charlestown Branch Sewer Medford-Somerville Branch Sewer Prison Point Pump Station Somerville Marginal CSO Overflow** Allison Hayes Pump Station Wakefield Branch Sewer

The Deer Island Treatment Plant receives North System flow from three remote headworks and the Winthrop Terminal headworks. The three remote headworks: Ward Street Headworks (256 mgd) located in Roxbury, Columbus Park Headworks (182 mgd) in South Boston, and Chelsea Creek Headworks (350 mgd) in Chelsea, have a combined pumping capacity of 788 mgd. The Winthrop Terminal Headworks (125 mgd) is located on Deer Island. The four North System headworks receive flows from interceptor lines or pump stations as follows: Ward Street Headworks South Charles Relief Sewer Charles River Valley Sewer North Charles Metro Sewer* Cottage Farm CSO* Columbus Park Headworks Boston Main Interceptor Dorchester Interceptor Chelsea Creek Headworks Alewife Pump Station North Metro Relief Sewer DeLauri Pump Station Caruso Pump Station Overflow Winthrop Terminal Headworks Winthrop Sewer Caruso Pump Station**

H.1.c Combined Sewer Overflow Facilities

The conditions for discharge of effluent from six CSO chlorination facilities are also included in MWRA’s Boston NPDES permit. One of these facilities, Constitution Beach in East Boston, was closed in September 2000, leaving five active permitted CSO facilities. These five facilities, Cottage Farm and Prison Point in Cambridge, Somerville Marginal in Somerville, and Fox Point and Commercial Point in Dorchester, discharge to the Charles River, the Inner Harbor, the Mystic River, Dorchester Bay and Dorchester Bay, respectively. Discharge of combined wastewater from a CSO treatment facility outfall to a receiving body of water is defined in this report as a CSO activation. Discharge of combined wastewater to a non-facility CSO outfall pipe is defined as a CSO overflow. CSO overflows will not be discussed in this report. In general, CSO activations occur as a result of heavy rain, snowmelt, or choking at the headworks.

H-7

Choking is the process by which the headworks restrict the flow to Deer Island. During wet weather, when the wastewater volume exceeds the hydraulic capacity of the treatment plant, the headworks “choke” the flow and hold the wastewater in the lines. As a result, the combined wastewater backs up into the system, forcing the combined wastewater to overflow to CSO treatment facilities and non-facility CSO outfall pipes, resulting in potential CSO activations and overflow as well as potential SSOs. In addition to choking in response to hydraulic demand on the system, the headworks may choke so that emergency repairs, system testing, or maintenance work can be performed at the treatment plant. Choking at Ward Street and Columbus Park Headworks influences Cottage Farm activations. Choking at the Columbus Park Headworks can influence activations at Fox Point and Commercial Point CSOs. Backups at the DeLauri Pumping Station brought about by choking at the Chelsea Headworks can activate the Somerville Marginal CSO. At the CSO facilities, the combined wastewater is screened and chlorinated prior to discharge. Of the five CSO facilities, only Cottage Farm and Prison Point have tank storage capacity. This allows the chlorinated wastewater to be held at these facilities. The facility only discharges when the storage capacity is exceeded; when that happens, the treated wastewater overflows and is discharged to the river. The three other CSO facilities are gravity CSO facilities, which means that combined wastewater arrives and leaves the CSO facility by gravity. This type of facility provides disinfection and allows the chlorinated combined wastewater to overflow to the receiving water as quickly as the wastewater arrives at the facility. The five CSO facilities provide treatment for approximately 50% of the CSO volume while the other half overflows in any of 80-plus permitted CSO overflow structures of the sewerage system without the benefit of any type of treatment. Of the more than 80 permitted CSO overflow structures, 53 are located in Boston, 15 in Cambridge, 5 in Chelsea, and 12 in Somerville. These outfalls discharge into Boston Harbor, the Alewife Brook, the Mystic River, the Charles River, and the Neponset River.

Cottage Farm CSO Facility During dry weather conditions, wastewater arrives at the Ward Street Headworks where it is pumped to the Deer Island Plant. Under storm conditions, wastewater backs up into sewer lines and into the Cottage Farm CSO facility. Cottage Farm detains wastewater up to a volume of 1.3 MG. Any excess flow is screened, settled, chlorinated, and discharged to the Charles River through outfall MWR201. Combined wastewater that is held back is pumped back to the Ward Street Headworks. This facility, on-line since 1971, has a design pumping capacity of 233 mgd. An upgrade completed in FY01 added a dechlorination system for the effluent.

H-8

Prison Point CSO Facility Prison Point is both a dry weather and storm water pumping station. The dry weather phase is a five-mgd capacity sewer pumping station that receives flow from the Boston Marginal Conduit and the Cambridge Marginal Conduit. Prison Point feeds into the DeLauri Pumping Station. The storm water phase has a maximum pumping capacity of 385 mgd. Treatment includes screening, disinfection, and detention. During wet weather, if the dry pumping capacity is exceeded, the combined flow is screened, chlorinated, and held in detention basins. Once the basins fill, treated flow is discharged downstream below the new Charles River Dam at outfall MWR203. Combined wastewater volume that is held back, up to 1.2 MG, is pumped back to the DeLauri Station. This facility came on-line in 1980 and was upgraded with a dechlorination system in 2001.

Somerville Marginal CSO Facility Somerville Marginal CSO is an unmanned gravity facility with a design capacity of 245 mgd. It receives wet weather flow from the northeast portion of Somerville and part of Medford. Normally, dry weather flow from these areas arrives at the DeLauri Station via the Somerville-Medford trunk sewers. During wet weather, combined sewer flow backs up to the Somerville CSO facility. Unlike Cottage Farm or Prison Point, this facility does not provide any large-scale detention capacity during storm conditions. Treatment consists of screening and chlorination. Effluent is discharged to the lower Mystic River basin at outfall numbers MWR205. The relief outfall, MWR205A, discharges to freshwater above the dam. MWR205A only activates under specific conditions and the vast majority of discharges are released through MWR205. During low-intensity rainfall when line capacity is not exceeded, the combined wastewater is pumped back from a wet well to the DeLauri Station. This facility came on-line in 1973 and was upgraded in 2001 with a dechlorination system. Figure H-2 on the following page shows a representative gravity CSO schematic applicable to Somerville Marginal as well as the Fox Point and Commercial Point facilities.

Fox Point CSO Facility Fox Point is an unmanned gravity facility with a design capacity of 119 mgd. It receives wet weather flows from the Dorchester Interceptor sewer line. Operation of this facility parallels that of the Constitution Beach CSO; treatment includes screening and disinfection. Effluent is discharged to Dorchester Bay through outfall number MWR209. This facility came on-line in 1989, and a dechlorination system was added in 2001.

Commercial Point CSO Facility Commercial Point is an unmanned gravity CSO with a design capacity of 194 mgd. This facility also receives wet weather backups from the Dorchester Interceptor. Treatment includes screening and disinfection. Effluent is discharged to Dorchester Bay through outfall number MWR211. This facility came on-line in 1991 and was upgraded in 2001 with a dechlorination system.

H.2 South System

The South System serves a population of about 700,000 people and is located to the south and southwest of Boston. The South System covers an area of approximately 237 square miles. Figure H-3 on the following page illustrates the South System hydraulic schematic. Community sewer lines tie into the South System through MWRA interceptor lines. The Framingham Extension Sewer, Wellesley Extension Sewer, Upper Neponset Valley Sewer, Wellesley Extension Relief Sewer, Neponset Valley Sewer, Walpole Extension Sewer, Stoughton Extension Sewer, Braintree-Randolph Trunk Sewer, and several other branch sewers discharge to the South System High Level Sewer. The High Level Sewer has a capacity of 360 mgd. Pump stations move the wastewater through the High Level Sewer to the Nut Island Headworks for preliminary treatment and grit removal. The South System flows are then conveyed to the South System Pump Station at Deer Island through the 4.7-mile Inter-Island Tunnel for treatment at the Deer Island Treatment Plant. In 2004 the MWRA completed the Braintree-Weymouth Intermediate Pump Station (IPS) in North Weymouth. The IPS pumps sewage from the North Weymouth Relief Interceptor directly into the Inter-Island Tunnel, bypassing Nut Island. The IPS also acts as a headworks with bar screens and grit collectors. The IPS was designed to increase South System capacity, helping to alleviate some of the overflows in the South System. Additionally, the IPS will pump by-products between the fertilizer palletizing plant in Quincy and Deer Island. Sewage sludge will flow from Deer Island to Quincy for conversion to fertilizer and centrate from the fertilizer production process will return to Deer Island for treatment through two pipelines associated with the IPS. Once at Deer Island, two force mains deliver the South System flow to one of two locations. The South System flow is normally discharged to the effluent channel of the Grit Facility, where it is combined with the North System and recycle flows, then split between Primary Clarifier Batteries A through D. The alternate discharge location is directly to the Primary Clarifier Battery D influent channel, which allows the South System flow to be isolated.

Eight MWRA pump stations move wastewater from low-lying areas to the High Level Sewer: Hingham Pump Station (16.5 mgd), Braintree-Weymouth Pump Station (60 mgd), Braintree-Weymouth IPS (45 mgd), Squantum Pump Station (12 mgd), Houghs Neck Lift Station (2.8 mgd), Neponset Pump Station (90 mgd), Framingham Pump Station (48 mgd) and Quincy Pump Station (52 mgd). The seven pumping stations receive flow from interceptor or community lines as follows: Hingham Pump Station Weymouth-Hingham Sewer Lines Braintree-Weymouth Pump Station Braintree-Randolph Trunk Sewer Braintree-Weymouth Extension Sewer Holbrook Extension Sewer Hingham Pump Station Braintree-Weymouth IPS North Weymouth Relief Interceptor Quincy Pelletizing Plant (see Chapter 4) Squantum Pump Station Squantum Sewers Houghs Neck Lift Station Houghs Neck Sewer Neponset Pump Station Neponset Valley Sewer Framingham Pump Station Framingham Sewers Quincy Pump Station Quincy and Upstream Sewers

H.2.a South System Pump Stations

H.2.b South System Headworks

The Deer Island Treatment Plant receives South System flow from the new Nut Island Headworks. The Nut Island Headworks went on-line on July 7, 1998. It is located in Quincy and has a capacity of 360 mgd. Vortex grit separators similar to those used on Deer Island in the North System Grit Facility provide grit removal for South System flows.

H.3 Deer Island Treatment Plant

Until July 8, 1998, wastewater flows from the North System were treated at the Deer Island Treatment Plant and flows from the South System were treated at the Nut Island Treatment Plant. In July 1998, the Nut Island Treatment Plant was decommissioned and all flows were treated at Deer Island. Four lines convey sewage to the Deer Island Treatment Plant. North System wastewater is delivered to the plant via the Boston Main Drainage Tunnel (from the Ward Street and Columbus Park Headworks), the North Metropolitan Relief Tunnel (from the Chelsea Creek Headworks), and the North Metropolitan Trunk Sewer. South System wastewater is transferred to the plant from the Nut Island Headworks and Braintree-Weymouth Intermediate Pump Station via the Inter-Island Tunnel. The Deer Island Treatment Plant receives wastewater at the North Main Pump Station (NMPS), the Winthrop Terminal, and the South System Pump Station (SSPS). The North Metro Relief Tunnel and the Boston Main Drainage Tunnel connect to the NMPS, which consists of ten pumps, each rated at 110 mgd, for a total pumping capacity of 1,100 mgd. The North Metro Trunk Sewer connects to the Winthrop Terminal. The Inter-Island Tunnel connects to the SSPS, which consists of eight pumps, each rated at 66.7 mgd, for a total capacity of 534 mgd. Grit removal and screening (preliminary treatment), which remove heavy particles and debris, is provided at the remote headworks and on-site at Deer Island. Flow from the South System receives preliminary treatment at the Nut Island Headworks. Grit and screenings are landfilled off-site. The upgraded primary treatment plant came on-line on January 21, 1995. The first battery of secondary treatment was initiated at Deer Island on August 1, 1997. Battery B came on-line on March 1, 1998, and the third and final secondary treatment battery, Battery C, started up on March 8, 2001. Wastewater from the North System flows through the grit chambers for additional grit removal. It, along with South System wastewater, then flows to the primary settling tanks where floatables, consisting mainly of oil, grease, and plastics rise to the surface while the sludge of heavy solid particles settles to the bottom. The majority of the primary effluent (the allowable capacity for secondary treatment) is sent to secondary treatment, while any remaining portion from high flow conditions due to rainfall bypasses secondary and is sent directly to the disinfection basins to be treated with sodium hypochlorite. Effluent from secondary treatment is then, if necessary, blended with primary effluent that bypassed secondary, and then sent to the disinfection basins, where it is chlorinated, detained, and then dechlorinated before discharge. The scum (floatables) is skimmed off the top of the primary and secondary settling tanks while the sludge (settled solids) is scraped from the bottom of the tanks. Primary scum is pumped to the scum concentrator while the primary sludge is pumped to the gravity sludge thickeners. Scum and sludge from the secondary batteries are concentrated using centrifuges. After the scum and sludge are concentrated and thickened, they are conveyed to the anaerobic digesters for further treatment. The digested sludge/scum is barged to the Fore

H-14

River Pelletizing Plant, where it is converted into fertilizer (refer to Chapter IV). Methane from the digestion process is stored and used to generate power and heat for DITP. Figure H-4 on the following page presents the Deer Island plant process flow diagram.

H.3.a Deer Island Treatment Plant Outfalls

On September 6, 2000, effluent from Deer Island was diverted to the new 9.5 mile outfall tunnel into Massachusetts Bay. Effluent is discharged through 53 operational risers over the last 1.25 miles of the tunnel. The tunnel has a capacity of 1,270 mgd, slightly greater than the old harbor outfall system. Before the effluent enters the outfall it is used to run a hydroelectric facility linked to the Deer Island power grid. Although sealed and non-operational, the old Deer Island harbor outfalls are subject to periodic inspections and remain available for emergency use. Effluent is channeled through a common conduit to four potential outfall pipes: 001, 002, 004, and 005

H.3.b Nut Island Outfalls

The former Nut Island Treatment Plant discharged treated wastewater through four outfalls. Although the Nut Island Treatment Plant no longer exists, outfalls 101, 102 and 103 remain operational in case of emergency at the Nut Island Headworks. These outfalls discharge to Boston Harbor; the new emergency spillway built concurrently with the new headworks discharges to Hingham Bay.

H.4 Collection and Transport System

An issue of concern in both the North System and the South System is the occurrence of Sanitary Sewer Overflows (SSOs). These occur during extreme rainfall events, when inflow and infiltration from heavy rains exceeds the capacity of the pipes, causing certain areas to become inundated. Whenever there is a high amount of rainfall, a crew from the Transport Department investigates a number of critical areas to visually monitor potential overflow sites. While some of these critical areas are the MWRA’s responsibility, most of them are the responsibility of the local communities. A list of these areas belonging to the MWRA is included in Table H-4 on page H-15. Not all of these areas are checked during every rainfall, and some are monitored by the MWRA only during extreme storm events. Table H-5 shows areas identified by MWRA staff as having the potential to overflow under certain conditions. SSOs have not, as of yet, occurred in these areas.

Appendix I: Instrument Detection Limits, Method Detection Limits, and Quantitation Limits

Overview An understanding of the detection limits of analysis is essential to reviewing

the data from chemical analyses. There are three different types of detection limits that are most often encountered:

• Instrument Detection Limits • Method Detection Limits • Quantitation Limits, also known as Reporting Limits.

I.1 Instrument Detection Limits

Instrument detection limits (IDL) reflect the capability of the instrument. This limit will be the lowest of the three detection limits. The IDL will not take into account the losses of the pollutant associated with the matrix (soil or wastewater) and extraction procedure. This discrepancy is known as matrix interference.

I.2 Method Detection Limits

Method detection limits (MDL) are the smallest amount of a substance that can be detected above background noise using a particular method. The MDL is statistically determined by running a series of analyses using various low concentrations of a pollutant. Using a Student's “T” test, the smallest concentration that has a 99% probability of being detected above the background is designated the MDL for that pollutant. The EPA, using several private laboratories, has determined what the MDLs are for most priority pollutants using their approved methods. These are published in the 40 CFR.

I.3 Quantitation Limits

In general, if a plot is made of pollutant concentration versus instrument response, it will show a linear relationship. As the pollutant concentration approaches zero, the linearity of the relationship is lost. At the point where the linearity is lost is called the Quantitation Limit (QL) or sometimes the Reporting Limit. In other words, the smallest concentration where the linear relationship holds is the smallest concentration that can be quantified. Generally, the QL is about five times the MDL. Quantitative limits are relevant to GC/MS analyses, that is, methods 608 (for pesticides), 624 (for volatile organics), and 625 (for semi-volatile organics). Specific limits are highly matrix-dependent.

I.4 Detection Limits, Non-Detects, and Reporting

In short, the IDL is the lowest concentration that a particular instrument can detect. The MDL is the lowest concentration that can be detected using a particular method. The QL is the smallest concentration that can be confidently considered to be accurate. Reported concentrations that are between the MDL and the QL indicate that a pollutant is present, but at a concentration too low to be accurately quantified. For example, using EPA method 624, chloroform has an MDL of 1.6 µg/L and a QL of 10 µg/L. If the concentration from an analysis is reported as 5 µg/L then it can be inferred that although the actual chloroform concentration in the

I-2

wastewater is uncertain, 5 µg/L is a best guess. The EPA requires that these intermediate values be flagged with a “J” on any reports submitted to them. Therefore, these are sometimes simply called “J-values.” For non-detects in analyses of metals, cyanide, petroleum hydrocarbons, etc., it is customary for “less than the MDL” to be listed as a result. For a non-detect in the 608, 624, and 625 analyses, “less than the QL” is typically listed. Often it becomes necessary to estimate a concentration for below detection limit values, specifically when calculating the average yearly concentration of a pollutant. A well-established method is to assume the actual concentration of a non-detected pollutant is simply one half of the MDL. While no scientific theory supports this assumption, it is more reasonable than assuming that the concentration is zero, or the MDL itself. The EPA and DEP also accept it as a standard practice that can be applied to any series of tests. This technique is utilized in this report. For the organic compounds – methods 608, 624, and 625 – one tenth of the QL, or half the MDL, was assumed for all non-detects (i.e. values below QL). For all metals, cyanide, petroleum hydrocarbons, etc., half the MDL was assumed for all non-detects (i.e. values below MDL). In Table I-1 is a list of the parameters regularly tested for in MWRA effluent. The required EPA method number, and the MDLs and reporting limits attained by the MWRA’s Central Laboratory are included.

Appendix K: Glossary, Abbreviations/Acronyms, and Units

K.1 Glossary

40 CFR Part 122 - Code of Federal Regulations: Protection of the Environment. Part 122 is Administered Permit Programs: The National Pollutant Discharge Elimination System. (Appendix D of 40 CFR 122 lists the Permit Application Requirements.) Acid Base Neutrals (ABNs) - A category of organic chemical pollutants also called semi-volatile organics. See Appendix K. Acute - A stimulus severe enough to rapidly induce an effect; in aquatic toxicity tests, an effect observed in 96 hours or less is typically considered acute. When referring to aquatic toxicology or human health, an acute effect is not always measured in terms of lethality. Acute Criteria- The maximum concentration of a constituent in water that an organism may be exposed to for a total of one hour, once over three years, without dying. Acute Static Toxicity Test - Test designed to measure water quality effect on mortality. It measures the effect of the whole effluent sample on an organism. Animals are put in a vial with effluent, and the fatal effects are monitored. To calculate water quality standards, the test is run on sensitive animals. The concentration that shows a 95% mortality rate is then multiplied by two. Activation - An event when the wastewater flow exceeds the holding capacity of the sewer lines and the hydraulic capacity of the treatment plant, causing a diversion of flow to the CSO facilities. Aeration - The process of adding air to a liquid (e.g. wastewater). Aliquot - A measured portion of a sample. Anaerobic Digester - The structure where organic material is broken down by organisms in the absence of oxygen. Anoxia - The absence of oxygen. Average Monthly Discharge Limitation - The highest allowable average of “daily discharge” over a calendar month, calculated as the sum of all daily discharges measured during a calendar month divided by the number of daily discharges measured. Average Weekly Discharge Limitation - The highest allowable average of “daily discharge” over a calendar week, calculated as the sum of all daily discharges measured during a calendar week divided by the number of daily discharges measured during that week. Bar Screen - A screen made of bars designed to catch large debris (e.g. rags, wood, shoes) in waterways. Below Detection Limit/Level (BDL) - Values below the Reporting or Quantitation Limit. For further explanation see Appendix K. Bioaccumulation - The process in which industrial waste, toxic chemicals, and other pollutants gradually build up in living tissues and organs. Biochemical - Having to do with a chemical change resulting from the metabolic activities of living organisms.

K-2

Biochemical Oxygen Demand (BOD) - The amount of oxygen needed to oxidize inorganic materials and to degrade organic materials by biochemical reactions in a certain time at a certain temperature. BOD is used as a measure of organic pollution. Biomagnification - The process by which the concentration of a compound increases in species occupying successive trophic levels. BDL - See Below Detection Limit Bloom - A large mass of algae (microscopic and or macroscopic) in water. BOD - See Biochemical Oxygen Demand. Buffering Capacity - Measures the ability of certain water bodies to resist changes in pH from addition of acidic or caustic substances. CFR- See Code of Federal Regulations Chemical Oxygen Demand (COD) - The amount of oxygen needed for the chemical oxidation of chemicals in water. COD is used to measure the suitability of water for organisms that require oxygen. Chlorination - The addition of chlorine or chlorine compounds to wastewater. Chlorination is most often done for disinfection purposes. Choking - A process by which flows that cannot be handled by existing pumps are “choked back” into the sewer system, frequently leading to local overflows. Chronic - A stimulus that lingers or continues for a relatively long period of time, often one-tenth of the life span or more. Chronic should be considered a relative term depending on the life span of an organism. The measurement of a chronic effect can be reduced growth, reduced reproduction, etc., in addition to lethality. Chronic Criteria - The maximum concentration of a constituent in water that an organism may be exposed to for a total of four days over three years without showing long term, harmful effects, short of mortality. Chronic criteria involve sublethal effects on, among other things, the growth, reproductivity, and fertility of organisms. Chronic Reproduction Test - A test designed to measure the chronic effects of wastewater on reproduction and fertility. Chronic Survival and Growth Test - Test designed to see if any mortality occurs after the chronic criteria have been passed. After the organisms have survived, the size of the animals are measured after seven days and statistically compared to controls. Clean Water Act (CWA) - Formally referred to as the Federal Water Pollution Control Act or Federal Water Pollution Control Act Amendments of 1972. Pub. L. 92-500, as amended by Pub. L. 95-576, Pub. L. 96-483, and Pub. L. 97-117: 33 U.S.C. 1251 et seq. COD - See Chemical Oxygen Demand Code of Federal Regulations (CFR) - Codification of the general and permanent rules of the federal government. CFR 40 covers environmental protection. Combined Sewer - A sewer receiving both sanitary wastewater and stormwater runoff. Combined Sewer Overflow Facility - A place where overflow from combined sewers is screened, settled, and chlorinated before being discharged. Combined Sewer Overflow Pipe - A pipe that discharges overflow from combined sewers in order to prevent back-ups in the sewerage system.

Criteria - The numerical and or narrative elements of water quality standards. Critical Dilution - Dilution of the effluent required to meet Water Quality Standards. CWA - See Clean Water Act. Daily Discharge - The discharge of a pollutant measured during a calendar day or any 24-hours period that reasonably represents the calendar day for purposes of sampling. For pollutants with limitations expressed in units of mass, the daily discharge is calculated as the total mass of the pollutant discharged over the day. For pollutants with limitations expressed in other units of measurements, the daily discharge is calculated as the average measurement of the pollutant over the day. Designated Use - Specified use of a body of water included in state water quality standards. Digester - A place where organic matter is broken down either with oxygen (aerobically) or without oxygen (anaerobically).

Eutrophication - The natural process by which a body of water ages. Nutrients stimulate plant growth and lakes, estuaries, and bays evolve into bogs or marshes. Effluents high in nutrients cause excessive plant growth that accelerates eutrophication. Fecal Coliform - Bacteria found in the wastes of warm-blooded animals. Fecal coliform is used as an indicator that disease causing bacteria and viruses are present. It is a component of Total Coliform. Floatables - Constituents of wastewater that rise to the surface in the settling process, consisting mainly of oil, grease, and plastics. Grab Sample - An individual sample collected in a period of less than 15 minutes.

Lethal Concentration 50% (LC50) - The concentration of effluent in a sample that causes mortality to 50% of the test population at a specific time of observation. Limiting Nutrient - In a given ecosystem, the limiting nutritional factor that controls the growth of plants or animals. Usually the limiting nutrient for plant growth is nitrogen in the marine environment and phosphorus in the fresh water environment.
